In the present embodiment, the display assembly 12 includes display arrays composed of Organic Light Emitting Diodes (OLEDs). The display assembly 12 may be used for display.
In this embodiment, the display module 12 is a transparent module, and the image capturing module located in the first region of the inner surface of the display module may capture an image through the transparent display module 12.
The display module 12 displays when the display module is in a bright screen state and does not display when the display module is in a dead screen state.
In this embodiment, the first region of the inner surface of the display module is disposed opposite to the image capturing module, and the first region covers the photosensitive surface of the image capturing module, for example, the photosensitive surface of the image capturing module faces the first region of the display module 12. The photosensitive surface is the collection surface of the image collection module, the collection surface is used for sensing the ambient light, and the image collection is carried out based on the sensed ambient light.
The image acquisition module can be a front camera in the mobile terminal.
The vertical projection of the first area where the image acquisition module is located on the display module is contained in the second area.
In some embodiments, the area of the second region is equal to the area of the first region, or the area of the second region is slightly larger than the area of the first region.
Because in this application display module assembly can enter into transparent state under the image acquisition state, so, the image acquisition module assembly can carry out image acquisition through gathering the module.
In the present embodiment, the polarization assembly 13 includes one or more polarization layers having a polarization function. Meanwhile, the transmittance of the polarizing assembly 13 itself is not high, and for example, the transmittance may be 50% or less, for example, 50% or 30% or less.
Polarisation subassembly 13 can reduce the inside that some ambient light incides display module assembly through low luminousness at first, and on the other hand can filter through the polarization effect from establishing display module 12 is to the reverberation of the ambient light formation of incidenting to make during the overwhelming majority of reverberation can not project the environment again, make the user can see the surface of printing opacity display module assembly and see display module assembly.
However, due to the low light transmittance of the light polarizing component 13, if the light polarizing component 13 is still disposed on the image capturing module formed by one or more cameras, the image capturing module cannot capture images, or the brightness of captured images is very low. Therefore, in the present embodiment, the light-deflecting element 13 specifically filters light in the display region other than the second region; therefore, the polarization assembly 13 is not located in the second region, and thus the image acquisition module can acquire images through the first region on the inner surface of the display module and the second region in the display module.
Therefore, if the display module 12 is in the screen-off state and the electrochromic module 14 is not disposed, the second area and the first area in the display area are color-different due to different light transmittances and unfiltered reflected light, or the transparency is poor, and even the image acquisition module or the display set is exposed through the second area.
In this embodiment, the second area is: a sub-region of the display area, and the sub-region corresponds to the first region. The second area can be a rectangular area, a circular area or an elliptical area which is equal to the area with the adaptive shape and size of the image display module.
The image capturing module mentioned in this embodiment may be a front camera of the display device. FIG. 2 shows: a second region and a display region other than the second region.
As shown in fig. 3A, when the image capturing module is in the non-image capturing state, the second area and the display area outside the second area are both in the bright screen state. Fig. 3A is a schematic diagram of a desktop.
Fig. 3B is a schematic diagram of the image capturing module located in the first area when the display module is in a screen-off state (i.e., a non-bright state). The display module assembly that this application embodiment provided is in under the screen state of disappearing, and the image acquisition module does not reveal, in order to signal the position relation of image acquisition module assembly and display module assembly in figure 3B, carries out the differentiation and shows, and the effect that figure 3B shows is not the actual effect of this application embodiment.

example 1:
when the display module provided by the example takes a picture (namely, image acquisition), the electrochromic material is in a transparent state, and light outside the display module enters the camera through the electrochromic material as far as possible. When the screen is lighted, the electrochromic material is in a transparent state, and light emitted by the OLED display screen (namely one of the display components) can penetrate through the electrochromic material, so that the display effect of the area where the camera (image acquisition component) is located is consistent with that of other areas.
When the OLED display screen is black, the color-changing material is in a closed state (dark color), external light cannot pass through the color-changing material, and the camera area is in a black state, so that the overall screen experience is greatly improved.
Under the mode of shooing (being in the image acquisition state of image acquisition module promptly), electrochromic material is in transparent state, and external environment light can get into the camera through color-changing material to guarantee the effect of shooing.
Under the OLED display screen display mode (namely in bright screen state), the electrochromic material is in transparent state, the camera area of the OLED display screen can normally display content, and the brightness of the screen is far higher than the brightness of reflected light of the camera, so that an actual user cannot see the camera, and the user can feel that the screen is a whole.
In the standby mode (namely in the screen-off state) of the OLED display screen, the electrochromic material is in an opaque state, ambient light cannot pass through the electrochromic material and is used for preventing the camera from being seen, and the whole screen is in a whole.
Example 2:
this example provides a display module assembly, in the camera area, inserts electrochromic material between the touch-control subassembly of display module assembly and cover glass. The polarizing plate having a polarizing effect in the polarizing assembly is cut off in the area, and the electrochromic material containing the SPD material is inserted in the position.
Example 3:
the present example provides a display module, in which an electrode layer of a touch device in a camera area is used as a lower electrode layer of a color-changing material, the color-changing material is sprayed on the touch device, and an upper electrode layer (corresponding to the first electrode layer) is sprayed on a bottom layer of a polarizer.

this example provides a display module assembly, in the lower electrode layer spraying of camera area on polarizing material substrate (this area removes polarizing material) upper strata, the electrode layer spraying of colour-changing material on the polaroid, upper electrode layer spraying is in the bottom surface of protective glass.
In summary, the display modules provided in examples 2 to 4 of the present application integrate the camera area and the non-camera area of the screen into a whole through automatic switching of the electrochromic material when the screen is dark and bright. When the camera works, the color-changing material is in a transparent state, and light rays penetrate through the color-changing material as far as possible and enter the camera, so that the photographing effect is not influenced. The camera can be a front camera, and the camera is the image acquisition module.
